Definitions

  • the invention relates to a housing for accommodating one or more conductor terminals which are designed as through connectors.
  • the invention also relates to a set of such a housing and one or more conductor terminals which are designed as through connectors.
  • Conductor terminals are available in the electrical sector in a variety of designs, e.g., as screw terminals, e.g., in the form of luster terminals, or as spring-loaded terminals, which have respective spring-loaded terminals for connecting electrical conductors.
  • Conductor terminals which are designed as through connectors are characterized in that they have at least two conductor terminals for joining and electrically connecting at least two electrical conductors.
  • the conductor insertion openings for these conductor connections are arranged on diametrically opposite sides of the housing of the conductor terminal.
  • the conductor terminals are available with differently designed housings, in particular with different external cross-sectional shapes.
  • the conductor terminals are not or only slightly protected against the penetration of dirt and moisture.
  • increased protection is required, especially against moisture.
  • a housing for an electrical plug connection is known, for example, from U.S. Pat. No. 3,680,036.
  • this object is achieved by a housing for accommodating one or more conductor terminals designed as through connectors, having the following features:
  • the housing has a tubular central receiving body, which is formed closed on the circumferential side and has at least one continuous opening extending from a first end face of the receiving body to the opposite second end face of the receiving body;
  • the continuous opening has an internal cross-sectional contour in at least one middle region in the axial direction middle region which is adapted with a predefined external cross-section shape to the outer contour of a predefined number of conductor terminals that are to be accommodated in the continuous opening,
  • the receiving body has a first thread on the first end face and a second thread on the second end face;
  • the housing has a first screw cap with a thread via which the first screw cap can be screwed onto the first thread on the first end face of the receiving body
  • the housing has a second screw cap with a thread via which the second screw cap can be screwed onto the second thread on the second end face of the receiving body.
  • the invention has the advantage that a housing, which is easy to use and to assemble for the user, for accommodating one or more conductor terminals in the form of through connectors is specified.
  • the housing can be formed with relatively few individual parts, which promotes a simple construction and simple assembly.
  • the housing is suitable for the realization of a simple and reliable sealing concept, in which there are no user errors.
  • the housing has a tubular central receiving body, which is formed closed on the circumferential side. This ensures a good shielding effect of the conductor terminals arranged in the housing or in the opening of the central receiving body against environmental influences. Due to the continuous opening, the conductor terminals are ensured to be easily received and/or attached in the receiving body.
  • the receiving body may be wholly or partially cylindrical on the outside, but it may also have other cross-sectional shapes on the outside.
  • the receiving body can have an inner cross-sectional contour in its internal opening, which is adapted to the outer contour of conductor terminals to be accommodated therein. This also promotes easy assembly for the user.
  • the conductor terminals arranged in the continuous opening can be reliably held and are also protected against vibration loads.
  • first and second screw caps can be connected to the central receiving body via a threaded connection.
  • first screw cap and/or the second screw cap each have a through opening for feedthrough of an electrical cable whose electrical conductors (insulated conductors) are connected to the conductor terminals arranged in the housing.
  • the first thread and/or the second thread can be formed as an external thread. This also promotes a simple and intuitive assembly of the parts of the housing.
  • the threaded connections can be dimensioned relatively large and accordingly have a high strength.
  • the first screw cap and/or the second screw cap may be formed in the manner of a union nut.
  • a strain relief for the electrical cable led through the passage opening of the screw cap may also be formed or arranged in a screw cap, for example by means of a clamping element having clamping lugs.
  • the receiving body may be one-piece or multi-part, for example in the form of a single injection-molded component or in the form of several injection-molded components.
  • the receiving body with the inner cross-sectional contour can be formed one-piece. This has the advantage that the assembly of the parts of the housing is particularly simple for the user, wherein the insertion of the conductor terminals is thereby also made particularly simple and ergonomic by the predetermined inner cross-sectional contour.
  • the continuous opening can have a constant internal cross-sectional contour in the axial direction. In this way, the conductor terminals to be inserted into the opening can be guided through the inner cross-sectional contour right at the beginning of the insertion process.
  • the inner cross-sectional contour of the continuous opening can have a star shape. This optimizes the use of space in the interior of the receiving body. Due to the star shape, longitudinal bars are also formed on the inside of the opening, which further increase the strength or rigidity of the receiving body.
  • the housing can have a first seal, which is pressable against the receiving body by means of the first screw cap by tightening the threaded connection of the first screw cap on the first end face, and/or the housing has a second seal, which is pressable against the receiving body by means of the second screw cap by tightening the threaded connection of the second screw cap on the second end face.
  • first seal and/or the second seal may be formed as a ring-shaped seal.
  • the first seal and/or the second seal may be formed rotationally symmetrically with an internal opening aligned with the continuous opening of the receiving body.
  • the first seal and/or the second seal can have a profile in an axial cutting plane, which has a radial branch and an axial branch protruding therefrom, wherein the radial branch extends predominantly in the radial direction of the receiving body and the axial branch extends predominantly in the axial direction of the receiving body.
  • the first seal or the second seal can create a good seal for both the separation plane between the respective protective cap and the receiving body and the cable that is passed through.
  • the radial branch of the respective seal can be pressed to the receiving body by means of the respective screw cap.
  • the axial branch can lie sealingly on the outer surface of a cable passed through the seal.
  • the seal has an L-shaped cross-sectional shape.
  • the first seal and/or the second seal may advantageously be made of an elastic material, for example of an elastomer such as rubber or silicone.
  • the housing can include the central receiving body, the first screw cap, the second screw cap, the first seal and the second seal. With such a five-part structure, the housing can be provided cost-effectively and is easily assembled by the user. In addition, a high mechanical robustness can be achieved.
  • the receiving body may have only one continuous opening. This allows for a particularly simple and ergonomic insertion of the conductor terminals into the continuous opening.
  • the first screw cap and/or the second screw cap in at least one region of its outer surface, can have a corrugation, a square contour and/or a hexagonal contour.
  • the receiving body may advantageously have a contour for attaching a tool on its outer circumferential surface, for example in the form of at least two opposing flattenings, so that a counter-hold can be ensured when tightening the screw caps.
  • a set made up of a housing of the type described above and one or more conductor terminals which are formed as through connectors, wherein the one conductor terminal or the plurality of conductor terminals can be accommodated form-fittingly in the continuous opening of the receiving body.
  • This also allows for the advantages described above to be realized. Due to the form-fitting accommodation of the conductor terminal or the plurality of conductor terminals, these are held at a defined position, wherein they can be held in the radial direction in particular with little play, so that they cannot bump excessively against the inner walls of the receiving body even under vibration loads.
  • One or more conductor terminals may each have spring-loaded terminals for connecting electrical conductors.
  • the spring-loaded terminals also ensure long-lasting, reliable contacting.
  • Such a spring-loaded terminal connection may, for example, have a clamping spring, wherein, depending on the design, a busbar may also be present.
  • the conductor terminal may have an actuating element, e.g., a swiveling actuating lever.
  • the undefined term “a” is not to be understood as a numeral. If, for example, a component is mentioned, this is to be interpreted in the sense of “at least one component”. If angles are given in degrees, they refer to a circular dimension of 360 degrees (360°).

  • FIGS. 1 and 2 illustrate that the housing 1 has a tubular central receiving body 2 , on the first end face of which a first screw cap 3 is arranged and on the second end face of which a second screw cap 4 is arranged.
  • the first screw cap 3 has an external hexagonal contour 31 in an area facing away from the receiving body 2 .
  • the first screw cap 3 has an axially continuous opening, through which a first cable 5 , for example a NYM cable, is passed.
  • the second screw cap 4 has an external hexagonal contour 41 in an area facing away from the receiving body 2 .
  • the second screw cap 4 has an axially continuous opening, through which a second cable 6 , for example a NYM cable, is passed.
  • the receiving body 2 has a first thread 21 in the form of an external thread on the first end face.
  • the first screw cap 3 has an internal thread 30 assigned to the first thread 21 , which is screwed onto the first thread 21 .
  • the receiving body 2 has a second thread 22 in the form of an external thread on the second end face.
  • the second screw cap 4 has an internal thread 40 assigned to the second thread 22 , which is screwed onto the second thread 22 .
  • a continuous opening 20 Inside the receiving body 2 is a continuous opening 20 .
  • a plurality of conductor terminals 9 are arranged, to each of which individual conductors of cables 5 , 6 are connected.
  • the first seal 7 has a radial branch 71 , which is pressed against the end face of the receiving body 2 by the tightened threaded connection of the first screw cap 3 .
  • the first seal 7 further has an axial branch 70 , which is sealed over a certain longitudinal section to the first cable 5 arranged therein. The same applies to the second seal 8 .
  • the second seal 8 has a radial branch 81 , which is pressed by the tightened threaded connection of the second screw cap 4 against the end face of the receiving body 2 .
  • the second seal 8 further has an axial branch 80 , which rests sealingly over a certain longitudinal section on the second cable 6 arranged therein.
  • FIG. 4 shows the described elements in cross-section.
  • FIG. 5 one can see the described elements of the housing 1 and the conductor terminals 9 and the cables 5 , 6 prior to assembly.
  • the assembly of the displayed elements can be carried out, for example, with the following assembly steps:
